3. focus points

The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.

6. maximum light sensitivity

With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.

15. Has phase detection autofocus for photos

A phase detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.
